Russell Knox: I'll prove Darren Clarke wrong about Ryder Cup selection

Russell Knox admits he is desperate to win the FedEx Cup to prove he should have been given a Ryder Cup wildcard.

Knox was overlooked by Europe captain Darren Clarke despite missing out on automatic qualifying by a single place and being ranked 20th in the world, comfortably higher than Clarke's choices of Thomas Pieters, Lee Westwood and Martin Kaymer.

The 31-year-old is currently seventh in the FedEx Cup standings on the PGA Tour -- Henrik Stenson is the next highest European at 21st -- and therefore in contention to win the overall title and $10 million bonus at the Tour Championship, which finishes just five days before plays gets under way at Hazeltine.

"It's certainly motivated me for the next three weeks, that's for sure," Knox said. "I have to use this as a springboard to try and win the FedEx Cup. I've never wanted to prove someone wrong so badly in my life I think.

"It's not sour grapes or anything. Darren had an extremely difficult decision and all of those three guys were worthy of a pick.

"When Darren called me it was obvious within one second that is wasn't going to be good news. It was a very short phone call. I didn't feel like I needed to ask any questions or give my opinion on anything. It was obvious that he had made up his mind and that was final. I respected his decision.

"I was very disappointed not have gotten the nod. But I'll use this as motivation over the next three weeks."

Clarke admitted he had wanted Knox to play in the Wyndham Championship a fortnight ago to try to qualify, but that Knox wanted to be "fresh" for the FedEx Cup.

"I hope the decision not to play Wyndham ultimately had nothing to do with it, maybe it did, but I'm sure no one will ever talk about that," Knox added. "I'm happy with the decision I made, I felt it was the best one for me and I don't think it would have made a difference anyway.

"It's going to be difficult for me to watch [the Ryder Cup] but I probably will and I'll be rooting for the team of course. I wish them all the best and hope they win.

"Of course I feel like I deserve to be there and should be playing but I'm not, so I have to respect the decision that's been made.

"Every year there's a guy in my position that doesn't get picked and it's a story right now, but in a couple of week's time when it all starts, I'm sure it'll be forgotten that I'm not in the team."

Clarke revealed he had suffered sleepless nights over his decision but ultimately "found it impossible" to leave Pieters off the team after the 24-year-old finished fourth in the Olympics and second in the defence of his Czech Masters title the following week, before winning in Denmark on Sunday.

"That call to Russell was as hard a phone call as I've ever had to make in golfing terms," added Clarke, who played with Pieters for the first two rounds in Denmark and saw him shoot a 62 on Thursday.

"Partly because I knew how much of a disappointment it would be, because in 2008, I won two weeks before the qualifying finished and it was my second win of the year and I didn't get a pick. So I know how much I was hurting at that stage."

With five rookies qualifying automatically, albeit one of them being Masters champion Danny Willett, Clarke had made no secret of wanting to "balance the team" with experienced players.

But the 48-year-old insisted Westwood had not been selected because of the pair's longstanding friendship, adding: "I selected him because he brings something that no one else can bring to the Ryder Cup. This is his 10th one.

"He will be somewhat like the general amongst the team. Anything he says, everybody sits up and listens.

"Yes, we have six rookies and yes, it's not like any other tournament. But the experienced guys will do what we do in the European way by looking after the first-time guys."
